Today, the waves are crashing onto the beach every 5 seconds. The times from when a person arrives at the shoreline until a crashing wave is observed follows a Uniform distribution from 0 to 5 seconds. Round to 4 decimal places where possible. The probability that the wave will crash onto the beach between 1 and 2.6 seconds after the person arrives is P(1 < x < 2.6) = The probability that it will take longer than 2.5 seconds for the wave to crash onto the beach after the person arrives is P(x ≥≥ 2.5) = Find the maximum for the lower quartile. seconds.

Let X luck variable show μ = 1, σ2 = 1 parameter lognormal distribution. So what is the probability P (X> 10)?
The lifetime of a supercapacitor manufactured by ELEMENT45 is exponentially distributed with mean lifetime of 1,000 hours. (b) (ii) If it is known that the supercapacitor has been working 950 hours, what is the probability that it will be working at least 1100 hours?
Today, the waves are crashing onto the beach every 4.3 seconds. The times from when a person arrives at the shoreline until a crashing wave is observed follows a Uniform distribution from 0 to 4.3 seconds. Round to 4 decimal places where possible. The probability that the wave will crash onto the beach between 0.8 and 2.3 seconds after the person arrives is P(0.8 < x < 2.3) = The probability that it will take longer than 1.86 seconds for the wave to crash onto the beach after the person arrives is P(x ≥≥ 1.86) = Find the minimum for the upper quartile. seconds.

The amount of time that a surveillance camera will run without having to be reset is a r.v. X having exponential distribution with = 50 days. Find the prob that such a camera (a) will have to be reset in less than 20 days. (b) will not have to be reset in at least 60 days.
Extralite are testing a new long-life bulb. The lifetimes, in hours, are assumed to be normally dis- tributed with mean u = 4650 and o = 400 (Round your answers to 4 decimal places): (a) Find the probability that a bulb chosen at random has a lifetime between 4250 and 4750 hours. (a). (b) Extralite wish to quote a lifetime which will be exceeded by 99% of bulbs. What time, correct to the nearest 100 hours, should they quote? (b)
Delivery times for shipments from a central warehouse are exponentially distributed with a mean of 2.81 days (note that times are measured continuously, not just in number of days). The standard deviation of an exponential distribution is equal to the mean of 2.81 days. A random sample of 65 shipments are selected and their shipping times are observed. Use the Central Limit Theorem to find the probability that the mean shipping time for the 65 shipments is less than 2.38 days.
May is tornado season in Oklahoma. According to the National Weather Service, the Poisson rate of tornados in Oklahoma in May is 0.7 per day, based on data from 1950 to the present. The meteorologist is interested in X= the time (in days) from the start of May until the 3rd tornado to occur. Which distribution is an appropriate model for the distribution of X? Gamma Poisson Exponential Beta
